Heat fixation is the procedure used to adhere a bacterial smear to a glass slide for viewing by a compound microscope. It denatures the proteins on the surface of the bacteria causing them to be sticky.
Heat fixation is to denature the bacteria and stick it to the slide. Think cooking an egg and forgetting to spray down the surface. Without that oil, the egg sticks, like the bacteria.

· Kills live cells of the organism - reducing pathogenic bacteria safe
· It causes the cells to adhere to the surface of the glass slide
· Changes the morphology of the cells, preparing them to readily accept stains/dyes
to kill the organism, make it adhere to the slide, and alter the organism so that they more readily accept stains (dyes). www.mansfield.Ohio-state.edu
a heat fix is something you put on the slide
It makes cells stick to the slide when rinsing.
adv..... heat fixing inactivates enzymes that would normally disrupt cell morphology and structure during staining and observation. dis....... if not done well much of the specimen can be destroyed in heat fixing.
If no heat fixing was done to a slide with a specimen on it, it would be rinsed off with the gram staining procedure. Heat fixing the specimen does kill specimen but it also locks it in place.

I guess so, and that's why you put out the flame after that.
it makes cell size shrink

When too much heat is applied during the heat fixing of a slide with a bacterial cell on it, the cell would explode. The membrane of the cell would rupture.

First and foremost, the purpose of heat fixing is to drive stain into the bacterial cells, which in this case, you are staining the background, so there is not a need for heat fixing. Next, the process of heat fixing will shrink the cell by a little. This sorts of support the first reason as since there isn't the need to heat fix, then don't. By not heat-fixing, we actually see a more accurate morphology, arrangement and size of thr bacterial cell. Hope that my answers helps 😊
